What is the Unique Registration Number NRA and how does it affect my listing in Spain?

If you're offering short-term rentals in Spain, it's now mandatory to register your property through a new national system and obtain a Unique Registration Number (NRA) for each unit. This guide explains what the NRA is, why it matters, and how to obtain and upload it to your Holidu listing.

What is the NRA and the Ventanilla Única Digital?

Understanding the NRA registration system is essential for all hosts operating short-term rentals in Spain:

The Ventanilla Única Digital de Arrendamientos is an official platform created by the Spanish Ministry of Housing. It centralizes the registration of all short-term rental properties in Spain, ensuring compliance with national regulations.
The NRA (Número de Registro de Alquiler) is a unique identifier that every property used for short-term rentals must have to be listed legally on any rental platform, including Holidu. Without this number, your listing cannot remain active on our platform.

How do I obtain a Unique Registration Number (NRA)?

Obtaining your NRA involves preparing the required documents and completing an online application through the official registrar's platform. Here's what you need to know:

Prepare your documents

Before you begin the application process, gather the following information:

Código Registral Único (CRU) - a 14-digit numerical code
Cadastral Reference (or Boat ID if applicable)
Any local license or tourist authorization required by your region

Note: Please be advised that there may be a fee associated with obtaining the NRA.

How to upload the NRA to your Holidu Account

Once you've obtained your NRA, you need to add it to your Holidu listing. There are two ways to do this:

Method 1: Through General Information Settings

Log into your Holidu host account
Select the property you want to update
Click on "General Information" and select "edit"
Scroll down to find the NRA field, enter your number, and click "Save"
Repeat this process for each of your properties

Method 2: Through the Top Banner Prompt

In your Holidu Host Account, you'll see a banner at the top of the page
Click on "Check the list" to access the NRA management page
Enter the NRA for each of your properties
Click "Continue" to confirm and save your entries

Important: If you see an error message, verify that your NRA format is correct. The NRA can have up to 53 alphanumeric characters and follows a specific structure.

NRA Format Requirements

If your Holidu account does not accept your NRA and shows an error message, ensure the format is correct. The NRA is composed of several fields that follow a specific structure with up to 53 alphanumeric characters. Verify each part complies with the official configuration to resolve any formatting issues.

Can I apply for an NRA on behalf of someone else?

Yes, you can apply for an NRA as an agency or property manager on behalf of a property owner. To do so, ensure you meet these requirements:

Attach a document proving you have legal authorization, such as a signed authorization with certified signature or a notarized power of attorney
Indicate the property owner's name in the "Person represented by the applicant" field on the application form

Can I apply for an NRA if my property has a temporary license number?

Yes, you can apply for an NRA if your property only has a temporary license number. As long as your license number is active in the local authority's registry, it will be accepted during the NRA application process. A temporary license simply means it is subject to review, but it remains valid for applying for the NRA.

Where to find the Código Registral Único (CRU)

The CRU is a 14-digit numerical code that you can find through several methods:

Request a Nota Simple from the Land Registry via https://sede.registradores.org
Use the Land Registry's Online CRU Finder
Check your Property Deed (Escritura); in some cases it may be listed as "Identificador único registral"

Troubleshooting: NRA Error Messages in Holidu

If your Holidu account rejects your NRA with an error message, verify the following:

The NRA format is correct and matches the official structure
All alphanumeric characters are entered accurately
The total character count does not exceed 53 characters
Each section of the NRA complies with the required configuration

If problems persist, review the official NRA format specifications to ensure accuracy before trying again.
